A first communication device receives a first data unit from a second communication device via one or more communication channels. The first data unit includes an indication of a first set of one or more sub-channels allocated to the first communication device, and the first data unit is configured to prompt the first communication device to transmit channel availability information as part of a subsequent orthogonal frequency division multiple access (OFDMA) transmission. The first communication device determines channel availability information for the one or more communication channels, and when the first communication device determines that at least one of the communication channels is idle, the first communication device transmits a second data unit to the second communication device in one or more sub-channels allocated to the first communication device as part of the OFDMA transmission, the second data unit including the channel availability information.

Determining channel availability for orthogonal frequency division multiple access operation

A first communication device determines one or more parameters related to a format of a media access control layer (MAC) data unit for an uplink (UL) multi-user (MU) transmission. The format of the MAC data unit for the UL MU transmission is different than a format of a MAC data unit for an UL single user (SU) transmission. The first communication device generates one or more data units that include the one or more parameters. The first communication device transmits the one or more data units to a plurality of second communication devices to inform the plurality of second communication devices of the format of the MAC data unit for UL MU transmissions by the plurality of second communication devices to the first communication device.

In response to determining that a Bluetooth inquiry phase or the Bluetooth paging phase will begin, a power save indicator signal is sent from a first communication device to a second communication device prior to a start of the Bluetooth inquiry phase or the Bluetooth paging phase. A gap between a first Bluetooth communication slot and a second Bluetooth communication slot is determined, and a time period within the gap is determined, where an end of the time period occurs at a defined amount of time prior to a start of the second Bluetooth communication slot. During the time period, one or more power save poll messages are sent from the first communication device to the second communication device, each first power save poll message prompting the second communication device to transmit a respective first WLAN packet to the first communication device.

Method and apparatus for maintaining a wireless local area network connection during a bluetooth inquiry phase or a bluetooth paging phase

A coexistence system including a first transceiver module, an interface, a second transceiver module, and an arbitration module. The first transceiver module, in a first network device, is configured to generate at least one first request signal. The first transceiver module operates according to a first wireless communication standard. The at least one first request signal requests transmission or reception for the first transceiver module. The interface is configured to generate a first priority signal based on the at least one first request signal. The first priority signal indicates a first priority level of first data signals corresponding to the at least one first request signal. The second transceiver module, in the first network device, is configured to (i) generate at least one second request signal, and (ii) generate a second priority signal. The second transceiver module operates according to a second wireless communication standard. The at least one second request signal requests transmission or reception for the first transceiver module. The second priority signal indicates a second priority level of second data signals corresponding to the at least one second request signal. The arbitration module is configured to (i) based on the first priority level and the second priority level, arbitrate the at least one first request signal and the at least one second request signal, and (ii) based on the arbitration of the at least one first request signal and the at least one second request signal, selectively connect antennas to the first transceiver module and the second transceiver module in one of multiple configurations.

Improvements associated with determining a location of a station device are described. According to one improvement, a method is performed by a network device. The method includes receiving a response packet from a station device, multiple times, as received signals by switching between a plurality of antennas of the network device during reception of each occurrence of the response packet. The received signals are converted to corrupted orthogonal samples. The response packet is received from the station device a final time as a final response packet via a single antenna of the plurality of antennas. Ideal orthogonal samples are re-generated based at least in part on the final response packet. Signal phase information, embedded in the corrupted and ideal orthogonal samples, is converted into estimated locations of the station device.

In response to determining that a Bluetooth inquiry phase or a Bluetooth paging phase is beginning, a power save (PS) mode signal is sent from a first device to a second device via a wireless local area network (WLAN) communication link, wherein the PS mode signal indicates that the first device is in a WLAN PS mode. A PS poll signal is sent from the first device to the second device via the WLAN communication link in a gap between Bluetooth inquiry phase message transmissions during the Bluetooth inquiry phase or between Bluetooth paging phase message transmissions during the Bluetooth paging phase.
